Manufacturer Aries Filter Works
Model Number AF-20-2015-BB
COMPATIBILITY & APPLICATIONS

Fits Standard 20" Big Blue Housings

The Aries AF-20-2015-BB fits any standard 20-inch Big Blue filter housing with a 4.5-inch inner diameter. This cartridge is designed for whole-house point-of-entry applications where chlorine, heavy metals, and taste/odor issues are present in municipal or well water supplies. The patented KDF-55 media handles the heavy lifting on metal ions and microbial control, allowing the coconut shell GAC to focus on organic contaminants and chlorine. Ideal for homes with high sediment loads, chloramine-treated city water, or heavy metal concerns. Replace every 12-18 months depending on water quality and household usage.

💧 Pro tip: KDF media works best in cold water applications and should be backwashed or agitated during initial installation to remove fine particles. If you notice a metallic taste in the first few days, flush the system for several minutes to clear residual zinc fines from the media bed.
